.To ali whom it may concerter' Be it knovvn that vie, Tatoos Refranero and Davie E. Raso, citizens oit the United States,

residing at Portland, 'in the count-y ot Multnomah and ont Gregori, have invented certain nea]w and useiiuiimlorovements in Driving Mechanism; andere do hereby declare the ioliovving to he a Itall, clear, and

. ot" one et the ground wheels and its mein driving Wheel. provided with a casingy acu cording to this invention. Fig. 2 is a crosssection, taken on the lineazw-' in Fig. i.. Fig. 3 is' a detail plan view of one oi the brackets which secure one casing disk to the trame, showing also the adjacent-.parts The motor oar or traction engine is provided. with two main road Wheels 2 of any approved construction, which are similar to each other, and which are mounted on the end portions oit a shaft 3. The shaft 3 is carried by the main frame 4l of the engine,

and the main frame has also similar hearings 5 in which the countershaft -6 is jour-A healed.A The .main driving Wheel is formed of an internal tocfthed ring 'Z having lugs 8 ou it, and 9 are brackets secured to the lugs 8 and to the periphery oi the ground Wheel 2. The countershat is preferably arranged ,y alcove the axis of the shaft 3 and a little in iront of it; and the countershaft 1s driven by means of any approved rnotor and intermediate driving mechanism. A toothed p1nion it? is secured on the countershaft and.

gears into the toothed ring, or' .Wheel 7. iihen arranged in this manner, and the mo- ,tor car V.is driven forwardly, the pressure of the pinion' on the '.teeth or" the' internal toothed Wheel is downward and between the main road Wheels and the steering Wheel or Wheels at the front end oi' the motor car.

iihis causes the steering yWheel or Wheels to.

:he ressed downwardly on the ground, as

vvel as engaging with the ground hy grav intervals. .metal is Varranged at the other side of the the revolutiouoi the driving pinion tends to raise the front end portion of the motor car od the ground. y

in order to prevent dirt and gravel :troni getting between the teeth of the inain Wheel and its pinion, and causing them to Wear out rapidly, the Wheel and pinion are inelosed in a casing which is made as nearly dirt proof as possible.

A stationary disk l of thin sheet metal is arranged on one side of the Wheel Z and its pinion. This disk i0 has a hole il in which the countershaft revolves, and itihas a hole 12 provided with a delige i3 Whicn is litted tightly over a projection lli on the -main frame around the inain shaft. rlhe periphery of the stationary disk 10 has a lateral dange l secured to' it, or :formed on it, and this .delige l5 incloses one edge of the toothed ring 7 and is fitted snugly'to it. Brackets 'i7' are provided for securing the stationary disk to the frame l at suitable A revolulole disk 18 of thin sheet Wheel Z and its pinion. This disk 18 has a hole 19 at its center'for the huh of the' ground Wheel to project through, and the disk is secured to a circumferential projection 20 on the said huh. The'center, part 21 of the disk i8 is dished inwardly toward the stationary disk, so as to clear the spokes of the ground Wheel, and its periphery is provided With a flange 22 which is litted tightly over and is secured to the toothed Wheel or ring 7, 'The-outer side of the road wheel 2 is closed 'hy a disk 24 which is secured to its periphery, and the inner side oit the road Wheel is closed by an annular plate 25 Iwhich is alsoseculed to the periphery and which is journaled on the ange l5 oit the stationary disk ll).

What We claim is:

l.. The combination, with a frame, a main shaft and a countershaiit carried by the fra-nie, a road Wheel mounted on the main shaft, an internal toothed Wheel` secured to the road Wheel, and a toothed pinion secured on the countershaft and gearing into the internal toothed Wheel; of a stationary disk provided with a peripheral ange which incloses one edge of the internal toothed wheel, said disk having holes for the said shafts, and a revolulole ,disk having its central portion secured to thehuh of the ground Wheel and having lits periphery secured to the interna-l toothed wheel.

lill? the road Wheel, and a toothed pinion sethe stationa disk and secured to the hub of the gro d Wheel, said revoluble disk having also a ange at its periphery which 1,5 rinoioses and is secured to the other edge of vthe internal toothed Wheel.

In testimony whereof We aiix our signatures, in presence of two Witnesses.
